Abstract

Abstract In this study, thermodynamic and economic analyses of binary fuel blends (E15, EA15, M15, MA15, and T15) using commercial gasoline as fuel and oxygenated fuel additives (ethanol, ethyl acetate, methanol, methyl acetate, and terpineol) at 15% by volume in a spark-ignition engine were performed. Performance and emission tests were carried out at various engine loads at a constant speed of 1500 rpm using commercial gasoline and five different fuel blends. Thermodynamic analyses were carried out on the test data. The augmentation in engine load caused an increase in exergy losses and a decrease in the unit cost of engine power exergy values. Specifically for gasoline fuel, the unit cost of engine power exergy at 25% engine load is 1.99 times higher than at 100% load. In fuel blends, the pump price of each fuel affects the fuel cost rate. Exergy efficiency in fuel blends increases with increasing engine load. The highest exergy efficiency is 19.58% for gasoline fuel at 100% engine load. It is 15.95% for M15 fuel at the same load. The exergy values of G100 and T15 fuel were closest to each other and T15 offered better energetic and exergetic performance than the other binary blends.

考虑热力学和经济分析的各种含氧燃料添加剂在火花点火发动机中的可用性研究

摘要在火花点火发动机中，以商品汽油为燃料，以含氧燃料添加剂(乙醇、乙酸乙酯、甲醇、乙酸甲酯和松油醇)为燃料添加剂，以15%体积对二元燃料混合物(E15、EA15、M15、MA15和T15)进行了热力学和经济分析。使用商用汽油和五种不同的混合燃料，在1500 rpm的恒定转速下，在不同的发动机负载下进行了性能和排放测试。对试验数据进行了热力学分析。发动机负荷的增加导致了火用损失的增加和发动机功率火用值单位成本的降低。具体到汽油燃料，25%发动机负荷时的发动机功率用能单位成本比100%负荷时高1.99倍。在混合燃料中，每种燃料的泵送价格影响燃料成本率。混合燃料的能源效率随着发动机负荷的增加而增加。在发动机负荷为100%时，汽油燃料的最高能效为19.58%。M15燃料在相同负荷下为15.95%。G100和T15燃料的火用值最接近，T15比其他二元混合燃料具有更好的能量和火用性能。

期刊介绍： Current energy systems need a vast transformation to meet the key demands of the 21st century: reduced environmental impact, economic viability and efficiency. An essential part of this energy revolution is bioenergy. The movement towards widespread implementation of first generation biofuels is still in its infancy, requiring continued evaluation and improvement to be fully realised. Problems with current bioenergy strategies, for example competition over land use for food crops, do not yet have satisfactory solutions. The second generation of biofuels, based around cellulosic ethanol, are now in development and are opening up new possibilities for future energy generation. Recent advances in genetics have pioneered research into designer fuels and sources such as algae have been revealed as untapped bioenergy resources. As global energy requirements change and grow, it is crucial that all aspects of the bioenergy production process are streamlined and improved, from the design of more efficient biorefineries to research into biohydrogen as an energy carrier. Current energy infrastructures need to be adapted and changed to fulfil the promises of biomass for power generation. Biofuels provides a forum for all stakeholders in the bioenergy sector, featuring review articles, original research, commentaries, news, research and development spotlights, interviews with key opinion leaders and much more, with a view to establishing an international community of bioenergy communication. As biofuel research continues at an unprecedented rate, the development of new feedstocks and improvements in bioenergy production processes provide the key to the transformation of biomass into a global energy resource. With the twin threats of climate change and depleted fossil fuel reserves looming, it is vitally important that research communities are mobilized to fully realize the potential of bioenergy.
